UPDATE - Friday 28 April: The algal bloom on the stretch of river from the Town Basin to Kaiwaka Point near the airport at Onerahi has cleared and there is no longer risk from contact with the water or fishing on it. 


An algal bloom is developing on the Hātea River in Whangārei and the public are advised to avoid contact with the water and refrain from fishing in the river until further notice.
